 * Name: initgroups
 *
 * Description:
 *   The group database /etc/group is read to determine all groups of which
 *   user is a member.  The additional group group is also added to this set,
 *   which is then used to set the supplementary group IDs of the calling
 *   process.
 *
 * Input Parameters:
 *   user  - Name of the user to query the /etc/group database for.
 *   group - Additional gid to add to the list of group IDs.
 *
 * Returned Value:
 *   The initgroups() function returns zero if successful, and -1 in case of
 *   failure, in which case errno is set appropriately.
 *
